I agree with this statement. Here's an analysis of the parts of the report that were redacted.
The Mueller report redactions, explained in 4 charts
Why parts of the Trump-Russia collusion section were redacted
There are four reasons Barr gave for why certain sections would be redacted, and good reasons for them:
- Revealing it would harm an ongoing matter. Ward writes, “Some redactions in the report will exist mainly to allow other related cases to continue unimpeded.”
- It reveals investigative techniques. Ward writes that “it’s highly likely the US government had to use sensitive spying methods — like, say, an undercover agent or top-secret surveillance technology — to investigate.”
- It reveals private information of third-party individuals. Ward writes the “Justice Department has long had a policy of not divulging people’s names during an investigation unless they are indicted.”
- It was obtained via grand jury testimony. This is secret by law.
So, I think that argument certainly holds for a part of the redactions. Here's where where they were in the document.
This reveals that
most of the ongoing matter redactions were in sections about Russian election interference and hacking.
There’s also a decent portion of material redacted because the “Justice Department has long had a policy of not divulging people’s names during an investigation unless they are indicted,” Ward writes.
But when it came to the section on the Trump campaign’s links and contacts with Russia, the primary redaction rationale was because the information was obtained through grand jury testimony.
Many of these redactions hide details about Trump associates’ interaction with Russian officials, like the section about the infamous Trump Tower meeting with Russia lawyer Natalia Veselnitskaya.

My conclusion is there is a rationale for not releasing some but not all of the information that was redacted.
